The term "route" includes two types of path from one place to another:
Routes have a beginning and an end and optionally some stops in between. Your device calculates your preferred type of path between all these points, for example, the fastest or most economical. You can edit a route by, for example, adding stops or moving the starting point. Routes can be imported but cannot be exported from your device.
Tracks also have a beginning and an end but no stops. Your device however has a fixed map-dependent path between these points and your device sticks to this fixed path as much as possible. You can only edit tracks using tools such as Tyre Pro. Tracks can be imported and exported from your device.
